Thermal conductivity measurement in laboratory – services

Chemical analysis Characterization of materials R&D support

You would like to perform a thermal conductivity measurement on your materials

Thermal conductivity is a material’s ability to transmit heat. Specifically, it’s a measure of the rate at which thermal energy flows through a material when subjected to a temperature difference.

Understand, compare and optimize the thermal performance of your materials

Thermal conductivity is a key parameter for ensuring the performance, safety, and durability of a material. Whether you are developing a new insulating composite, a high-performance thermal alloy, or a temperature-sensitive medical device, mastering this property is essential.

Our technical resources for thermal conductivity measurement

Laser Flash Method (LFA)

Obtaining high-precision thermal diffusivity over a wide temperature range

Hot Disk Method

Additional measurement to complete the conductivity calculation.

The FILAB laboratory performs thermal conductivity measurement

In what context should a thermal conductivity measurement be performed?

Measuring thermal conductivity allows you to:

  • choose a heat-dissipating or insulating material
  • size a thermal system (electronics, battery, motor, etc.)
  • understand abnormal heating
  • verify compliance with a standard or specifications
  • compare several formulations or suppliers

This data is essential in many sectors: energy, aeronautics, electronics, transportation, medical devices, etc.

FAQ

What materials can be analyzed by measuring thermal conductivity?

Thermal conductivity measurement applies to a wide variety of materials, whether solid, porous, flexible, rigid, or in powder form. At the filab laboratory, our versatile analytical equipment allows for the precise characterization of:

  • Metals and alloys: aluminum, copper, steels, high-temperature alloys, etc.
    Ideal for evaluating heat dissipation or comparing different grades.
  • Polymers: thermoplastics, thermosets, elastomers, biopolymers, etc. With the ability to study the effects of filler, crystallinity, or aging.
  • Composite materials: carbon fibers, glass fibers, etc. Including anisotropic materials where conductivity varies with orientation.
  • Technical ceramics: oxides, nitrides, carbides, technical glasses, etc. Suitable for insulating or high-conductivity materials.
  • Foams and porous materials: polymer foams, metallic foams, insulation materials, etc. Since the microstructure strongly influences conductivity, our techniques are adapted accordingly.
  • Powders and granules: ground polymers, metallic powders, mineral fillers, etc. Relevant for material testing before extrusion, injection molding, or additive manufacturing.
  • Glasses and glass-ceramics: transparent materials, technical glasses.
  • Fluids: oils, technical oils, heat transfer fluids, unpolymerized resins, gels, etc.

In short, virtually all material families can be analyzed, from solids to liquids, from bulk to powder, with a method adapted to each specific case.

 

 

La mesure de la conductivité thermique s’applique à une très grande variété de matériaux, qu’ils soient massifs, poreux, souples, rigides ou sous forme de poudre. Au laboratoire filab, notre parc analytique polyvalent permet de caractériser précisément :

  • Les métaux et alliages : aluminium, cuivre, aciers, alliages haute température…
    Idéal pour évaluer la dissipation thermique ou comparer plusieurs nuances.

  • Les polymères : thermoplastiques, thermodurcissables, élastomères, biopolymères…
    Avec la possibilité d’étudier l’effet de la charge, du taux de cristallinité ou du vieillissement.

  • Les matériaux composites : fibres de carbone, fibres de verre …
    Y compris les matériaux anisotropes où la conductivité varie selon l’orientation.

  • Les céramiques techniques : oxydes, nitrures, carbures, verres techniques…
    Adapté aux matériaux isolants ou à haute conductivité.

  • Les mousses et matériaux poreux : mousses polymères, mousses métalliques, isolants…
    La microstructure influençant fortement la conductivité, nos techniques s’y adaptent.

  • Les poudres et granulés : polymères broyés, poudres métalliques, charges minérales…
    Pertinent pour le contrôle matière avant extrusion, injection ou fabrication additive.

  • Les verres et vitro-céramiques : matériaux transparents, verres techniques.

  • Les fluides : huiles, huiles techniques, liquides caloporteurs, résines non polymérisées, gels…

En résumé, quasiment toutes les familles de matériaux peuvent être analysées, du solide au liquide, du massif à la poudre, avec une méthode adaptée à chaque cas.

Can measurements be taken at high temperatures?

Yes, some methods like LFA allow measurements up to several hundred degrees.

Can you support an R&D project?

Yes, we carry out complete test plans: microstructure/performance correlations, formulation optimization, post-aging evaluation…
